WO3 Ceramic Electrical Property

A large number of experimental studies suggest that the appearance of non-linear electrical characteristics a certain relationship to WO3 two-phase coexistence at the normal temperature, it’s believed that coexistence phase will affect the matching of crystal lattice, so that the grains have different dielectric responses. Samples sintered in air have coexistence structure of monoclinic and drilling inserts suppliers triclinic two-phase, having a non-linear current characteristic, and the samples sintered in a hydrogen atmosphere only have monoclinic structure, of which the voltage characteristics are linear, but also to some prove the extent of the conjecture that phase coexistence of WO3 ceramics at room temperature led to the production of Schottky barrier, so that the WO3 ceramics have nonlinear voltage characteristics.
